UNIT (5) Momentum 5.D Change in Momentum DATE NAME Scenario A 10 kg box, initially at rest, moves along a smooth horizontal surface. A horizontal force is applied to the box. The magnitude of the force changes as a function of time as shouwn. Take the positive direction to be to the right. Tme (econd Data Analysis Rank the magnitude of the impulse applied to the box by the force during each 2-second interval indicated below: PART A: A. 0-2 seconds B. 24 seconds C. 4-6 seconds D.6-8 seconds E.8-10 seconds Smallest impulse Greatest impulse Write a few sentences justifying your reasoning. Use words like speed, velocity, acceleration, time, force, momentum, and impulse. PART B: Using Representations PART C: Re-represent the data given in the force vs. time graph in Part A as a momentum vs. time graph for the same 10 kg box. Step 1: Identify the equation that relates force and momentum. Step 2: How can momentum be found from a force vs. time graph? Step 3: Plot the momentum as a function of time. (Make a table if you need to.) 10Time (s) Momentum (kgm/s) Forte Newtons) 5.D Change in Momentum Quantitative Analysis Use the graph above to calculate the velocity of the box after 10 seconds. For each line in the calculation, explain what was done mathematically. The first line is done for you. Ap = mai The change in momentum is equal to the mass times the change in velocity. UNIT 5.
